Abstract : Free-mode methods in component mode synthesis techniques are improved by the use of the concept of 'positive static' residuals, which are developed according to the theorems given in this paper. The technique of assembly of complicated structures is also presented. The convergence of the improved free-mode method is related to the so-called 'eigenfrequency coefficient n', which is generally greater than 1.0 and smaller than 1.4. (Author)
